‚ portDS.delayMechanism: 01h (we do only Delay request-response, aka End-to-End)
‚ portDS.logMinPDelayReqInterval: -3 (equal to portDS.logSyncInterval)
‚ transparentClockDefaultDS.delayMechanism: 01h (we do only End-to-End)
‚ transparentClockDefaultDS.primaryDomain: 127 (same as defaultDS.domainNumber)
